EXTENSION TABLE.

Application filed October 15, 1925. Serial No. 62,614.

This invention relates to furniture, particularly to tables and has for its object the provision of a dining table of the extension type provided centrally with a rotatably mounted portion upon which may be placed condiment or dishes of food or the like to be served, this rotatable portion or serving table being normally flush with the remainder or major portion but being provided with means whereby it may be elevated so as to be capable ofbeing turned by thoseseated about the table or by an attendant.

An important object is the provision of a table of this character which is extensible whereby to accommodate a greater or less number of persons, the serving portion or auxiliary table at the center being likewise extensible in accordance with the degree of extension of the main portion.

Another object is to provide a table of this character equipped with peculiarly constructed means which is very simply operable for the purpose of elevating the central or serving portion above the plane of the major portion so as to facilitate turning the same.

A further object is to provide a table of this character in which all the various parts are connected by means of mortise and tenon joints of a dove-tail nature whereby all the parts are adequately secured without the employment of screws, nails, glue or other auxiliary or extraneous devices, an advantage of this construction being that the various parts may be readily disassembled for convenience in transportation or storage.

'An additional object is to provide a table of this character which will be comparatively simple and inexpensive in manufacture, easy to set up and use, positive in action, eflicient and durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings. in which:

Figure 1 is a side elevation of the table. Figure 2 is atop plan view thereof. Figure 3 is'a vertical cross section with the central or serving portion in normal or lowered position.

Referring more particularly to the drawings, I have shown the table as comprising a pedestal 1 which may be of any desired shape in cross section and of any desired size and material. Located at the bottom of this pedestal are leg members 2 preferably equipped with casters 3 to facilitate moving the table about from place to place. These leg members are preferably held in place by means of dove-tailed tongues 4: thereon fitting within corresponding grooves 5 in the pedestal, the arrangement being such that the grooves 5 open out to the lower end of the pedestal so that the tongues 4 on the leg members may be easily slid thereinto and be retained in position without the 7 employment of any securing means whatsoever. Located at opposite sides of the upper end of the pedestal 1 are the main horizontal supporting members 6 which extend in spaced parallel relation and which are held in position as tor instance by means of dove-tailed tongues 7 thereon fitting within correspondingly shaped grooves 8 formed in opposite sides of the pedestal. These supporting members 6 have the tongues 7 extending only at the central portion thereof and these tongues are inserted within the grooves in the pedestal by sliding the members (3 laterally with respect to the pedestal. In' order to prevent subsequent accidental longitudinal movementof the members 6, use may be made of pins 9 or the like which pass through the pedestal and through suitable holes in the members 6 as will be readily apparent. "he upper edges or the end portions ot the members 6 are formed with dove-tailed tongues 10 which fit within correspondingly shaped grooves 11 atthe lower edges of the members 12 which are arranged transversely with respect to the members (3 and which are provided at opposite sides with dove-tailed tongues 13 and 14:. Disposed against the onter sides of the members 12 are other members 15 which have their faces toward the members 12 formed with dove-tailed grooves 16 receiving the time tailed tongues 13, and disposed against the inner sides of the members 12 are members 17 having their sides toward the members 12 formed with dove-tailed grooves 18 slidably receiving the dove-tailed tongues 14. It will be observed that the grooves 16 and 18 terminate short of the ends of the members 15 and 17 respectively so that while the members 15 and 17 are slidable with respect to the members 12 and to each other they will have a limited sliding movement so that they cannot become entirely separated. The upper co es of the members 15 and 17 are for ned with dove-tailed tongues 19 and 20 respectively for a purpose to be described and with notches 21 and 22 like wise for a purpose to be described.

Secured to one side of the pedestal, as for instance by means of dowel pins 23, screws or the like, is a horizontal supporting board provided at its outer ends with an upwardly extending flange member 25 having a hole 26 therethrough tor a purpose to be described. The upper end of the pedestal 1 is formed with spaced parallel grooves 27 which are likewise for a purpose to be described.

The table top comprises two sections designated generally by the numerals 28 and each top member comprises a ring-like portion 29 of semi-circular shape provided at its underside with a depending skirt or flange 30. The flanges or skirts of the sections are held to the top by means of locking devices 31 clearly indicated in Figure 14:, which locking devices are of double dovetailed tongue formation including members 32 and 33. These locking members are applied by having the portions 32 thereof fitting within correspondingly shaped grooves tl i. in the underside of the table top and with the portions 33 extending through correspondingly shaped notches or grooves 35 in the depending skirt or flange members. One of the depending skirt or flange members is provided with a cutout portion 36 for the accommodation of the upstanding member 25 at the outer end of the horizontal supnorting board 21 so that, in effect, the memher 25 will constitute a continuation of the depending skirt or flange when the two sections ot the table top are in contacting relation as illustrated in the drawings.

At their undersides, the sections 28 of the top are formed with dove-tailed grooves 37 and 38 receiving the dove-tailed tongues 19 and 20 on the members 15 and 17 respectively. Securing is efl'ected by means of suitable wedge members 39 and 40 which are engaged respectively within the notches 21 and 22. It will therefore be seen that each section of the top is secured with respect to one member 15 and one member 17 and siidable with respect to the other two, so that the two sections of the too may be slid apart to permit the insertion of extra leaves between them for increasing the size 01 the table. Owing to the fact that the grooves 10 and 1S terminate short of the members 15 and 17 and that the tongues 13 and 11 terminate short of the ends of the member 12 the separation or the two sections or the top is limited so that they cannot be pulled entirely apart and disconnected from the pedestal and other stationary part accidentally.

As stated above the top 01 the table is really of ring-like formation in order to provide a central circular opening 41 having a rabbeted edge Fitting within this opening is a circular central member or serving table which is formed of two similar semi-circular sections 44 having rabbeted edges normally engaging upon the rabbeted edges 1-2 of the opening so that the top of the central table portion will be flush with the top of the main table. This central section or portion comprises a supporting member of a block-like nature indicated at 45 formed at opposite sides with dove-tailed extensions 16 upon which are engaged side members t? mortised thereonto and provided at their outer and inner sides with dove-tailed tongues 48 and 49 respectively fitting within corresponding grooves in bar members 50 and 51 formed at their upper edges with dove-tailed tongues 52 and 53 respectively fitting within corresponding grooves in the underside of the sections 41-1. Each section l'l is secured to one bar and the opposite bar 51 by means of suitable wedges 5i and the other section being slidable with respect to these bars and similarly secured to the other two. By this construction it will be evident that the sections 44 of the central portion of the table may be pulled apart to effect extension thereof in accordance with the extension of the sections of the major portion of the table top. A suitable auxiliary leaf 56 may be inserted between the sections 44 when they are separated, as will be readily apparent.

The entire auxiliary or central member is pivoted with respect to the remainder of the table by means of a bolt or spindle 57 which extends through the block member 45 and into a suitable socket in the upper end of the pedestal 1.

Mounted on the spindle 57 is a plate member 58 which may be of disk-like formation carrying a plurality of bearing balls 59 engaging within a suitable race 60 in the underside of the member 45 so as to permit the central portion or serving table member to rotate freely. At its lower side the member 58 is formed, with grooves 61 within which are slidably engaged the inclined or wedge shaped arms 62 of a preferably U- shaped yoke 63 with which is connected a rod 64 slidable through a guide opening in the upstanding member 25 carried at the end of the support 24, this guide opening being the one above described and referred to by the numeral 26. Pivoted intermediate its ends upon a supporting bracket 65 is a lever 66 which has one end pivotally and slidably connected at 67 with the rod 64 and which has its other end similarly pivotally and slidably connected with a push rod 68 slidable through a guide opening 69 in the upstanding member 25.

In the use of the table, it is of course apparent that the major portion thereof is operated in exactly the same manner as any other extension table and that the central or serving table portion thereof may likewise be extended or contracted, as may be desired in accordance with the extension or contraction of the major portion. However, it is intended that condiment, food to be served or other matter be placed upon the central table member which, as above stated, may be rotated to bring the desired articles before any person seated at the table. Under normal circumstances, this central or serving table portion fits within the opening 41 and is flush with the top of the major portion of the table, but when it is desired to effect rotation it is merely necessary that someone press the rod 64 inwardly whereupon the arms of the U-shaped yoke 63 riding in the grooves 61 and 27 will act to lift the member 58 which rotatably supports the central or serving table portion. This lifted position is illustrated in Figures 4 and 5 and it is readily apparent that the serving table portion may be'easily rotated.

When it is not desired to effect rotation of the central or serving table portion it is merely necessary to press upon the push rod 68 so that the lever 66 will operate to move the rod 64 outwardly, the U-shaped yoke then travelling from beneath the supporting member 45 and permitting the central or serving table portion to be lowered to its normal position.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a comparatively simple and inexpensive table structure which is fully extensible to accommodate large or small parties and which has the great convenience of being equipped with the rotatably mounted serving table portion. Attention is directed to the fact that there is an absence of nails, screws and other securing devices, all the various parts being connected firmly and permanently by means of the mortising or drove-tailed groove and joint connections. It is believed that the construction, operation and advantages will be readily apparent to one skilled in the art without further explanation.

While I have shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I claim 1.
